So I’ve configured voice service a number of times, but never using Cisco equipment. There’s a business starting up here on Orcas Island and they need a number of lines voice and fax service. I had a spare 2801 router laying around and heard that it’s possible to provision voice service using these machines. So I looked on eBay for a module that will provide more than two FXS ports and decided on the VIC-4FXS<\/a>. When it was delivered, I installed it and booted the router. It told me that it needed a PVDM DSP Module<\/a>, so I got one of those as well. It has arrived. I have installed it. Now when I boot the router, I don’t get a warning or an error.<\/p>\n
